## Architecture
```
┌─────────────────────────────────────────────────────────┐
│ UI Layer (screens/, components/) │
│ - Screens and UI components │
│ - Only renders, no business logic │
│ - Calls store methods, observes state │
├─────────────────────────────────────────────────────────┤
│ Adapters (hooks/, controllers/) │
│ - Thin adapters between UI framework and stores │
│ - useAuth(), useProfile(), etc. │
├─────────────────────────────────────────────────────────┤
│ Core (core/) │
│ - Business logic lives here │
│ - Stores orchestrate everything │
│ - MUST be framework-agnostic │
│ - Could be extracted to CLI/API without changes │
├─────────────────────────────────────────────────────────┤
│ Infrastructure (infrastructure/) │
│ - Implements ports (interfaces) from core │
│ - Database adapters, external API adapters │
│ - Can be swapped without touching business logic │
└─────────────────────────────────────────────────────────┘
